Lava Bed In Yosemite National Park

The Yellowstone volcano is very active volcanic system which requires much observation. The geysers, mudd pots, hotsprings and steam vents are all examples of the heat from molten rock of a volcano. For many years the Yellowstone volcano could not be located. There is not obvious signs of a volcano, but scientists looked for other clues. Rhyolite is present in a location that has pinetress and many mosquitoes can be found due to the lakes that have formed. Rhyolite is a very violent eruption, due to the high silica content,  it flows slowly, like honey, and tends to pile up and form lava

Yosemite National Park, is a beautiful piece of nature it is a 195 mile nature getaway from the urban life that is lived San Francisco, CA and 315 miles away from the fast pace and overwhelming life that is lived in Los Angeles CA. This place is like no other in the beauty of its nature. The park is “747,956 acres, and is the home to hundreds of wildlife species and thousands of Yosemite plants” (U.S. Nat. Park Service). Yosemite is known for so many beautiful features, from its granite cliffs, waterfalls, clear streams, giant sequoia groves and biological diversity. And also for its two rivers which are the Tuolumne and Merced rivers. These rivers begin in the park and flow as far as west to the

The west coast of North America has been tectonically and volcanically active for billions of years. The Sierra Nevada Mountains in eastern California were born of volcanoes, and magma has been erupting in the Long Valley to the east of the mountains for over three million years (Bailey, et. al., 1989). However, the climactic eruption of the region occurred relatively recently in the region's geologic history. About 760,000 years ago, a huge explosion of magma warped the Eastern Sierra into the landscape that exists today. The eruption depleted a massive magma chamber below the earth's surface so that the ceiling of the chamber imploded, forming what is now known as

The Wyandotte caves are made out of limestone like any other cave in Indiana but the Wyandotte cave has a “cliff ”so when people go they have to be careful. There is a Mount Baldy in California but the one in indiana is special. Mount Baldy isn't a mountain, it’s a sand dune. Sand dunes are mountains hills and ridges with sand on them and they “Hide” behind beaches and are affected by tides. In other words Mount Baldy is a mountain with sand on it. Mount Baldy is also known as the “living” sand dune, because every year it is someplace new, South of the shore of Lake

Yosemite National Park is a national park located in Northern California, attracting countless tourists from countries all across the world for its luscious green landscape, beautiful waterfalls, and variety of different hiking trails. However it is known by many for far more than its physical beauty, and a deep history and significance have created the national park that Americans love today.

The granite formation to the left of Half Dome is El Capitan. This vertical rock formation extends about 3,000 feet (900 meters) from base to summit along its tallest face. View a timelapse of the webcams.

According to chapter 49 in Geology of National Parks, rocks in these parks mainly consists of some metavolcanic rocks, early Mesozoic metasedimentary along with batholiths made of granite from the Cretaceous period. Also, glacial sediments cover the bedrock in deep valleys and at high elevations. There are also avalanche cutes on the west side of Mount Whitney in the Sequoia National Park which occurs after an avalanche carrying trees, ice, even trees moves down a steep slope leaving behind a smooth path(pg.742). Most of the preexisting rocks in the Sierra Nevada area were destroyed the batholith intrusions, but separate granite intrusion separate curtains or sheets of metamorphic rock called roof pendants which can be found in both the Sequoia and Kings Canyon National Parks. According to the article, “Geology of the Sierra Nevada,” these batholiths are what remains from ancient volcanoes, and the intrusive igneous rocks form underground as the minerals in the molten rock cools down slowly.

It is minimal realized that lying underneath one of The United States biggest and most beautiful National Parks - Yellowstone Park - is one of the biggest "super volcanoes" on the planet. Every year, a huge number of guests come to respect the hot springs and fountains of Yellowstone, the Nation's first national park. Few are mindful that these miracles are powered by hotness from a vast repository of incompletely liquid rock (magma), simply a couple of miles underneath their feet. As this magma-which drives one of the world's biggest volcanic frameworks climbs, it pushes up the Earth's hull underneath the Yellowstone Plateau.

Yosemite area was formed by the action of tectonic movement and volcanic activity. It caused the heated magma that was below the pacific and the North American plate to be exposed (Yosemite National Park:The Kingdom of Granite and Glaciers). Further tectonic activity exposed the hidden magma exposing the valley. Yosemite Valley is cut from a granitic rock of the Sierra Nevada Batholith. Sedimentary and metamorphosed rocks, also known as roof pendants, comprise approximately 5% of the park’s landforms. Due to erosion on master joints, valleys, and later canyons are formed. The tendency of crystals in plutonic rocks to exfoliate, which acts on the granitic rock, is responsible for the formation of domes.

President Calvin Coolidge designated Lava Beds as a national monument in 1925. The National Park Service has been managing the park since 1933. From 1935 to 1942, Civilian Conservation Corps crews built most of the roads, trails, and services that allowed people to start visiting Lava Beds. Lava Beds is over 47,000 acres of nothing but beautiful land. This makes it a medium sized park compared to other national parks, but with all the history and nature to explore outside and over 700 caves to explore underground, there is enough to do at the park to keep you busy for over a week or more! Over half of Lava Beds is designated wilderness, where only people on foot can visit.About 100,000 visitors come to the park a year. It's pretty busy there in the

Lava flows of rhyolite and basalt have flowed through parts of Yellowstone as recently as 70,000 years ago. These lava flows destroyed everything in their paths while moving slowly at a rate of a few hundred feet per day, flowing months, or sometimes even several years. They are thick and cover as much as 130 square miles. They have nearly filled the Yellowstone Caldera, and spilled beyond the caldera’s border. These lava flows are responsible for forming four of the nine named plateaus in

The cave is underground and dark; it consists of human beings who have been living down there since childhood. These people are almost like prisoners since

Lava can pour out of the top of volcanoes and it can pour out of natural tunnels also known as lava tubes. The Volcano is called Kilauea. The lava was coming out from a lava tube near the Kamokuna ocean entry. When a huge 26 acre lava delta  fell into the ocean On New Year's Eve, the tube was left out in the open air. The collapsing lava delta caused big waves to form and massive explosions. After that, the lava started to flow into the ocean,

known volcanoes, 70 can be expected to erupt each year with at least one large eruption each

Did you know that in 1984 the largest cinder cone Moana Loa erupted and killed over 90 people. There is many many volcanos in the world. Volcanos release lava that can burn and melt Homes,Buildings, basically everything. They can injure people or sometimes kill. There is 3 volcanos that I will be talking about today.
